TG, first of all, on the main page your subject line reads, "Question about JB's Massive..."
I was a little wary of launching my cals that high too. He
is known for recommending higher amounts than most. But his p+c/ p+f strategy seems to keep the fat off!
With any drastic change in calorie intake, you should take anywhere from 7-10 days to ramp up or down to the amounts recommended. Perhaps even longer if it's extreme. Don't forget that all of these things are intended to take effect over longer periods of time, so using an extra week or two to prep yourself isn't a bad thing. So add an extra 100 cals a day for three or four days, see how it feels, stick with that surplus of 400 cals for a couple days, then try adding 100 more. If after a week you really can't imagine stomaching more, stick with your current amount. After 10 days or so, if you've already gained weight (and check whether your BF% has gone up too!) then you can gauge which direction to move your cals. If you have NOT gained weight, then keep on until you reach JB's numbers!
Hope that helps some.
Also, if it means anything to you, before I had to stop StB, I put on 9 pounds in 9 weeks, and my bf% did not change.

Short of robbing a bank, I couldn't afford to continue, although I dearly wish I could! (Robbing a bank might buy me a few more weeks on StB, but eventually I'd likely end up in jail, and I hear they don't separate p+c/p+f for you, unless you do, uh... certain favors for the cooks... and I'm not
that dedicated to mass gain! [img]tongue.gif[/img] )
*Is that your midsection in your avatar? If so... damn!!! I think those lines (the ones we call "penis lines", which obviously are not penis lines for you... I guess you can think of something more appropriate for them... I mean I do have a name or two, but maybe I shouldn't post them here... I'll just call them visible hip lines) are very sexy! Your man is a lucky bastard!
